1 Vortech, 2 Vortech, how many vortechs?

[bluegrass_reef12]

I have a 27 gallon cube that has been running for a little over 2 months now. Have been starting to add more and more corals and focusing the tank on some easier SPS corals for now. Check out my build thread.

I have a MP10 mounted on the back wall of the tank. I plan on adding more SPS coral, should I add another MP10 to the back wall on the opposite side? Add one to the side of the tank so the pumps face perpendicular?

Would a Nero 3 be a better option to add?

Or is the one MP10 enough by itself? I currently have it running in reefcrest maxing out around 70%.

Mp10 should be sufficent for a 30g cube.

the reefcrest mode is a bit underkill for most IMO.
